I'm pretty sure that msdos puts pipe files on the current working
drive, although I could be wrong and it puts them on the system boot
disk.  It's for sure that it puts them on my c: drive 
(harddisk) using msdos v3.1, 3.2, 3.21, and 3.3 (yes, I've tried 'em
all).  My machine is a few hundred miles away right now or I'd
check...

After thinking about it for a minute, I'd be amazed if msdos didn't
just put it in the default drive.  If it didn't, then your
write-protected dos disk would cause pipe failures all the time.  Of
course, not many people I know has write-protected their disks, but
one guy I know has done it and he seems to have no problems with
pipes (dos disk in A: and some other disk in B:, obviously, or he
would have had problems!).  Besides, if it did not operate this way,
they probably would have made some kind of a PIPESPEC entry in
CONFIG.SYS.  They did this for COMMAND.COM so that the system ran
cleaner when bringing it up on hard disks and the like.
